Patented Feb. 18, 1941 PATENT OFFICE SMOKING PIPE OR THE LIKE Henry Davenport Bellin, Providence, R. I., assignor to Davenport Ltd. Incorporated, Providence, R. I., a corporation of Rhode Island Application February 10, 1940, Serial No. 318,360

Claims.

The invention relates to smokers equipment such as pipes, cigarette holders and cigar holders and is shown in connection with a pipe, the principal object of the invention being to provide a 5 simple, inexpensive and eflicient connection between the mouthpiece and the stem of the pipe or the like of such nature as to permit easy removal of the mouthpiece for cleaning purposes, simply by pushing forwardly on said mouthpiece and turning the same to a predetermined position.

Another object of the invention is to provide a stem clean-out linger which is operable by forward pushing of the mouthpiece.

l5 With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.`

Figure 1 is a longitudinal sectional view partly in elevation showing the parts assembled for use.

Figure 2 is a view showing the mouthpiece and parts connected thereto pushed forwardly.

Figure 3 is a View similar to Figs. 1 and 2 but illustrating the manner in which the mouthpiece and parts connected thereto may be rearwardly withdrawn.

Figure 4 is a disassembled perspective view showing a number of the parts included in the above described views.

Figure 5 is a perspective view of the stemcarried sleeve.

Figure 6 is a fragmentary view similar to portion of Fig. 1 but showing a modification.

Figures 7, 8 and 9 are detail views showing further variations.

In the drawing above briefly described, the numeral 1 denotes a sleeve having a relatively large cylindrical rear end 8 and a comparatively small cylindrical front end 9, the latter being receivable in the rear end of a stem I0, such as a pipe stem. The sleeve portion 9 may be externally roughened as indicated at II in Fig. 5 to be tightly cemented in the stem I0 or it may be provided with screw threads or other means for holding it in place.

A relatively short longitudinal slot I2 and a comparatively long longitudinal slot I3 are formed in the small sleeve end 9, and both of said slots open through the front extremity of said sleeve end. The slot I2 is provided with a closed rear end I4 while the slot I3 extends rearwardly into the large sleeve end 8. .v

A mouhpiece I5 is provided with a forwardly projecting smoke tube I6 which is secured thereto in any appropriate manner. The front extremity of the mouthpiece I'5 is received in the rear portion of the enlarged sleeve end 8 and may be forwardly slid therein as will be clear from Fig. 2. The smoke tube I6 is provided with a key, I'I 5 in Figs. l to 4 and I1 in Fig. 6, said key being normally seated in the short slot I2. A coiled spring I8 is disposed in the large end 8 of the sleeve 'I around the tube I6 and said spring exerts a lrearward force on the mouthpiece I5 and the l0 smoke tube to hold the key I'I or I1' against the closed rear end I4 of the aforesaid slot I2. It is preferable that a Washer be provided to abut the front end of the spring I8. In Figs. 1 to 4, a

washer I9 is shown, connected with a thin sleeve 15* 20 which surrounds the aforesaid spring I8. In

Fig. 6, a plain washer I9 is illustrated. In this view, I have also illustrated another washer 2| abutting the rear end of the spring I8 and the I front end of the mouthpiece I5, whereas in Figs. 2'0' 1 to 4, the spring I8 simply abuts the front extremity of said mouthpiece.

I have shown a screw plug 22 threaded into the front end of the smoke tube I6 and having a l head 23, from which a stern clean-out finger 24 25 projects forwardly. In Figs. l to 4, a washer 25 surrounds the plug 22 and is clamped against the front extremity of the smoke tube I6 by the head 23, said washer being held against turning -by providing it with a lug 26 receivable in a notch 30 2'I in said smoke tube. The washer 25 is secured to the front end of the key I1 to anchor the latter, and the rear end of said key is provided with a hook 28 which is hooked into a small opening 29 in the smoke tube. In the present disclosure, 35 the key I1 spans the smoke admission opening 30 which is formed radially in the smoke tube I6 but said key is suiiiciently narrow to prevent obstruction of said opening 30. By fastening the key by means of the washer 25 and hook 28, 40 manufacture and assembly are facilitated.

In Fig. 6, the key Il' simply has its ends passed through openings in the smoke tube, said ends being clinched as shown at 3|. l

Th mouthpiece and stem are normally proper- 45 1y connected to permit use of the pipe or the like and whenever the stem clean-out ringer 24 is to be operated, it is simply necessary to push forwardly on the mouthpiece I5, thus forwardly moving the smoke tube I6 and said finger 24 with 50 respect to the stem Ill. Whenthe forward pressure on the mouthpiece I5 is relieved, the spring I8 immediately restores the parts to normal. Whenever it is desired to detach the mouthpiece and parts connected therewith from the stem 55 for cleaning, said mouthpiece is pushed forwardly at least as far as shown in Fig. 2, moving the key I1 or II out of the slot I2, and this same movement operates the finger 24 to clean the stem. The mouthpiece is then turned to align the key with the long slot I3 which ext-ends into the large end 8 of the tube 1. Thus, the mouthpiece and connected parts may be rearwardly withdrawn as shown in Fig. 3, the key then traveling through said slot I3. Reassembly may be effected with equal ease by a reversal of these operations.

While excellent results may be obtain-ed from the details shown and described and they are preferably followed, variations may of course be made within the scope of the invention as claimed. As examples, attention is invited to Figures '7, 8 and 9. In Fig. 7, a hook 28a is shown l on the rear end of the key I 1, said hook being in the form of a ring for reception in the smoke inlet 30, which construction may well be used instead of that illustrated more particularly in Fig. 4, if desired.

Figure 8 shows that the front end of the slot I2 may be flared as indicated at I2' to facilitate insertion of the key I'I or II. Obviously, the slot I3 may be flared in the same manner and for the same purpose.

In Figure 9, a cupped washer ISa is shown corresponding to the washer I9' of Fig. 6. The internal portion of the sleeve 'l which abuts this washer I9ab may be somewhat concave as shown. When the spring I8 pushes the washer I9a forwardly into tight contact with they coacting portion of the sleeve 1, a very effective air `seal is provided to prevent the entrance of any more air than necessary when smoking. The washers I9 and I9 are also, of course, held forwardly against the coacting internal portion of the sleeve 'I by the spring to exclude air as much as possible.

I claim:

1. In a pipe or the like, a sleeve having a relatively large rear end and a relatively small front end, the latter being insertible into the rear end of a stem, Vsaid small front end of said sleeve having two circumferentially spaced longitudinal slots both of which open through the front extremity thereof, one of said slots being closed at its rear end, the other of said slots extending rearwardly into said large rear end of the sleeve,
